SECURITIES PURCHASE AGREEMENT 

This Securities Purchase Agreement (the “Agreement”) is entered into as of December 19, 2016, by and among Equity
Bancshares, Inc., a Kansas corporation (the “Company”), certain selling stockholders of the Company, severally and not jointly and severally, listed on Annex A hereto (collectively, the “Selling Stockholders”
and each, a “Selling Stockholder”), and the purchasers, severally and not jointly and severally, listed on signature pages hereto (collectively, the “Purchasers” and each, a “Purchaser”). 

BACKGROUND 
 The
Company and the Selling Stockholders, severally and not jointly and severally, desire to sell, and each Purchaser desires to purchase, shares of the Company’s Class A common stock, par value $0.01 per share (the
“Class A Common Stock”), on the terms and subject to the conditions contained herein. 
 The issuance
and sale of the shares of Class A Common Stock hereunder is being made in a private placement, without registration under the Securities Act or any other applicable securities Laws (as defined below), in reliance on one or more exemptions from
registration and other requirements thereunder. 
 Therefore, in consideration of the foregoing, and the representations, warranties,
covenants and conditions set forth below, the parties hereto, intending to be legally bound, hereby agree as follows: 

1.    Purchase and Sale of Class A Common Stock. 

1.1    Sale and Issuance of Class A Common Stock. 

(a)    Subject to the terms and conditions of this Agreement, each Purchaser agrees, severally and not
jointly and severally, to purchase at the Closing (as defined below) that number of shares of Class A Common Stock set forth on such Purchaser’s signature page hereto, and the Company and the Selling Stockholders, severally and not jointly
and severally, agree to sell and issue an aggregate of 1,090,000 shares of Class A Common Stock, which shall consist of (i) 770,000 shares of Class A Common Stock to be issued by the Company and (ii) 320,000 shares of the Company’s
Class B common stock, par value $0.01 per share (the “Class B Common Stock”), which shall convert into an equal number of shares of Class A Common Stock upon transfer to the Purchasers in








 
accordance with Section 1.1(d), set forth opposite such Selling Stockholders’ names on Annex A hereto, to the several Purchasers at the Closing, at a purchase price of $32.50
per share (the “Purchase Price”). The shares of Class A Common Stock (including the Class B Common Stock converted into Class A Common Stock) to be issued and sold by the Company and the Selling Stockholders to the
Purchasers pursuant to this Agreement are collectively referred to herein as the “Shares.” 

(b)    The aggregate Purchase Price to be received by the Company and each of the Selling Stockholders
shall be equal to the total number of Shares sold by such party multiplied by the Purchase Price. 

(c)    Notwithstanding the foregoing, nothing in this Agreement shall be construed to permit or require any
Purchaser to purchase a number of Shares that would cause the Purchaser, together with any other person whose Company securities would be aggregated with the Purchaser’s Company securities for purposes of any banking regulation or law (or for
purposes of any securities regulation or law or any NASDAQ rule), to (i) violate any banking regulation, (ii) file a prior notice under the Change in Bank Control Act (the “CIBC Act”), or otherwise seek prior approval of
any banking regulator, (iii) become, or be required to register as, a bank holding company or otherwise serve as a source of strength for the Company or any Subsidiary, or (iv) cause the Purchaser, together with any other person whose
Company securities would be aggregated with the Purchaser’s Company securities for purposes of any banking regulation or law (or for purposes of any securities regulation or law or any NASDAQ rule), to collectively be deemed to own, control or
have the power to vote securities which would represent more than 9.9% of any class of voting securities, or 25.0% of total equity, of the Company outstanding at such time, or 4.9% of any class of voting securities of the Company outstanding at such
time if such Purchaser was a bank holding company. Clauses (i) through (iv) are referred to as the “Ownership Limitations”. If, but for this sentence, the purchase of Shares at the Closing would otherwise cause any Purchaser to
exceed any Ownership Limitation, then the number of Shares to be purchased by such Purchaser hereunder at the Closing shall be automatically reduced by the minimum amount necessary to ensure that no Ownership Limitation is exceeded by such Purchaser
at Closing (in which case such Purchaser’s aggregate Purchase Price shall be proportionately reduced). 

(d)    With respect to any shares of the Company’s Class B Common Stock being offered and sold by
the Selling Stockholders pursuant to this Agreement, each of the Purchasers hereby elect to receive an equal number of shares of Class A Common Stock in accordance with the terms hereof and the Company agrees to cause such shares of
Class A Common Stock to be issued to the Purchasers pursuant hereto. 
 1.2    Closing. The consummation of
the purchase and sale of the Shares and other transactions contemplated hereby (the “Closing”) shall take place at the offices of Norton Rose Fulbright US LLP, 2200 Ross Avenue, Suite 3600, Dallas, Texas 75201, at 9:00 a.m. Dallas
time, as promptly as practicable (but no more than three business days) following the first date on which all conditions set forth in Section 6 and Section 7 hereof have been satisfied or waived
(other than those conditions that by their nature are to be satisfied by actions taken at the Closing), or at such other time and place as the Company, the Selling Stockholders and the Purchasers shall mutually agree (the date that the Closing
occurs, the “Closing Date”). At the 

  
 - 2 - 








 
Closing, (i) the Company and the Selling Stockholders shall deliver, or cause to be delivered, to each Purchaser (or its designated custodian per its delivery instructions) one or more stock
certificates (or facsimiles or .pdf scanned copies of stock certificates with physical stock certificates to follow) registered in the name of the Purchaser, or in such nominee name(s) as designated by the Purchaser in writing, representing the
number of Shares set forth on the signature page hereto and bearing an appropriate legend referring to the fact that the Shares were sold in reliance upon exemptions from the registration requirements of the Securities Act and (ii) upon receipt
of the facsimiles or .pdf scanned copies of stock certificates, each Purchaser shall deliver, in immediately available funds, the full amount of the Purchase Price for the Shares being purchased hereunder by wire transfer to an account designated by
the Company at Equity Bank, which funds the Company will cause to be distributed promptly to the accounts specified in writing by the Selling Stockholders and the Company, respectively. For purposes of clarity, the Purchaser shall not be required to
wire its aggregate Purchase Price until it (or its designated custodian per its delivery instructions) confirms receipt of its Shares. The Company will promptly substitute one or more replacement certificates without the legend at such time as the
registration statement filed by the Company pursuant to the terms of the Registration Rights Agreement between the Company and each Purchaser, the form of which is attached hereto as Annex B (the “Registration Rights
Agreement”). The name(s) in which the stock certificates are to be registered are set forth on signature page hereto. 

2.    Representations, Warranties and Covenants of the Company. The Company represents and warrants to, and covenants with, each

Act). To the Company’s Knowledge, there exist no facts or circumstances (including without limitation any required approvals or waivers or any circumstances that may materially delay or prevent the obtaining of accountant’s consents) that

of the Shares by the Purchasers.

decision to purchase the Shares. Each Purchaser further acknowledges that it has had the opportunity to consult with its own counsel, financial, tax, and other professional advisers as it believes is sufficient for purposes of its purchase of the
Shares. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 2 hereof or the right of each Purchaser to rely thereon.

and accuracy of the foregoing representations, acknowledgements, and agreements.

the Purchaser a certificate representing such Shares that is free from all restrictive and other legends.

when the Company must suspend the use of the prospectus (the “Prospectus”) forming a part of the registration statement to be filed pursuant to the Registration Rights Agreement (a “Suspension”) until such time as
an amendment to such registration statement has been filed by the Company and declared effective by the Commission, or until such time as the Company has filed an appropriate report with the Commission pursuant to the Exchange Act. Without the

directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Shares, nor will such Purchaser engage in any short sale that results in a
disposition of any of the Shares by such Purchaser, except in compliance with the Securities Act and the rules and regulations promulgated thereunder and any applicable state securities laws. Such Purchaser agrees that it will not effect any
disposition of the Shares or its right to purchase the Shares that would constitute a sale within the meaning of the Securities Act or pursuant to any applicable state securities laws, except as contemplated in the registration statement to be filed

4.11    Ownership. Assuming the accuracy of the representations and warranties of the Company and the performance
of the covenants and agreements of the Company contained herein, the purchase of Shares hereunder shall not cause such Purchaser, to its Knowledge, together with any other person whose beneficial ownership of Company securities would be aggregated
with such Purchaser’s beneficial ownership of Company securities for purposes of any bank regulation or law, to collectively be deemed to own, control or have the power to vote securities which (assuming, for this purpose only, full conversion
and/or exercise of such securities by such Purchaser) would exceed any of the Ownership Limitations.

commitments, as may be amended from time to time, entered into by the Purchaser) which is materially and unreasonably burdensome on the Company’s business following the Closing or on the Purchaser (or any of its affiliates) or would reduce the

Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person, which the Indemnified Party believes
in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor or indemnitors hereunder (the “Indemnifying Party”) written notice of such claim or the


  
 - 24 - 








 
commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party
hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and
settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to
defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the
settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s
possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted
liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such
asserted liability; provided, however, that the Indemnified Party shall be entitled (a) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (b) if (i) the Indemnifying
Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (ii) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified
Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be
deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the
expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any
indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance
by, the Indemnified Party. 
 8.6    Termination of Conditions and Obligations. The restrictions imposed by
Section 4.8 upon the transferability of the Shares shall cease and terminate as to any particular number of the Shares upon the earlier of (i) the passage of one year from the effective date of the Registration
Statement covering such Shares, (ii) at such time as an opinion of counsel satisfactory in form and substance to the Company shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities
Act, and (iii) at such time as the Shares become eligible for resale by the Purchaser without any volume limitations or other restrictions pursuant to Rule 144(b)(1)(i) under the Securities Act or any other rule of similar effect.

date that is ten (10) calendar days following the date of this Agreement; provided, however, that the right to terminate this Agreement under this Section 9.1(b) shall not be available to any party whose breach of any
provision of this Agreement shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to such date or the failure of a condition in Section 6 or
Section 7 hereof to be satisfied at such time; 
 (c)    by any Purchaser (with
respect to the obligations of such Purchaser), any Selling Stockholder (with respect to the obligations of such Selling Stockholder), or the Company, upon written notice to the other parties, in the event that a Governmental Authority has issued an
order, decree, or ruling or taken any other action permanently restraining, enjoining, or otherwise prohibiting the consummation of the transactions contemplated by this Agreement and such order, decree, ruling, or other action has become final and
nonappealable; provided, however, that the right to terminate this Agreement under this Section 9.1(c) shall not be available to any party whose breach of any provision of this Agreement shall have been the cause of,
or shall have resulted in, such order, decree, ruling, or other action; 
 (d)    by any Purchaser (with
respect to the obligations of such Purchaser), upon written notice to the Selling Stockholders and the Company, if (i) there has been a breach of any representation, warranty, covenant, or agreement made by the Selling Stockholders or the
Company in this Agreement, such that the conditions to Closing set forth in Section 6.1 and Section 6.2 hereof, as applicable, would not be satisfied; and (ii) such breach is not cured (if
curable) within ten days after delivery of such notice; provided that this Section 9.1(d) shall only apply if such Purchaser is not in material breach of any of its obligations under this Agreement; or

forth in Section 7.1 and Section 7.2 hereof, as applicable, would not be satisfied and (ii) such breach is not cured (if curable) within ten days after delivery of such notice; provided
that this Section 9.1(e) shall only apply if the Company or such Selling Stockholder, as applicable, is not in material breach of any of its obligations under this Agreement. 

9.2    Effect of Termination Prior to Closing. In the event of termination of this Agreement as provided in
Section 9.1 hereof, this Agreement shall become void and have no effect without any liability or obligation on the part of any party hereto as to which such 

  
 - 26 - 








 
termination has been duly effected (other than the provisions of Section 8 and Section 10 hereof and this
Section 9.2); provided, however, that nothing herein shall relieve any party from any liability for any breach by such party of its representations, warranties, covenants, or agreements set forth in this
Agreement prior to such termination.

regard to choice of Law or principles that could require the application of the Laws of any other jurisdiction. 

10.4    Submission to Jurisdiction; Venue; Waiver of Trial by Jury. Each party agrees that it will bring any action
or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in any federal or state court of competent jurisdiction located in the State of Kansas (the “Chosen
Courts”), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any

provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement

defense based on adequacy of any other remedy, whether at Law or in equity, that might be asserted as a bar to the remedy of specific performance of any of the terms or provisions hereof or injunctive relief in any action brought therefor. 

  
 - 28 - 








 10.6    Severability. If any provision of this Agreement or the
application of any such provision to any person or circumstance shall be declared by any court of competent jurisdiction to be invalid, illegal, void, or unenforceable in any respect, all other provisions of this Agreement, or the application of
such provision to persons or circumstances other than those as to which it has been held invalid, illegal, void, or unenforceable, shall nevertheless remain in full force and effect and will in no way be affected, impaired, or invalidated thereby.
Upon such determination that any provision, or the application of any such provision, is invalid, illegal, void, or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the
parties hereto as closely as possible to the fullest extent permitted by Law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the greatest extent possible. 

10.7    Entire Agreement. This Agreement, including the Annexes hereto, constitute the entire agreement between the
parties hereto with respect to the subject matter hereof and supersede all prior written, and prior and contemporaneous oral, agreements and understandings between the parties with respect to the subject matter hereof.

any person other than the parties hereto, or their respective successors and permitted assigns, any rights, remedies, obligations, or liabilities under or by reason of this Agreement. 

10.9    Headings; Interpretation. All headings and subheadings used in this Agreement are used for convenience only
and are not to be considered in construing or interpreting this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by the phrase “without limitation.” The meanings given
to terms defined herein will be equally applicable to both the singular and plural forms of such terms. Unless expressly provided to the contrary, the word “or” is not exclusive and “hereunder,” “hereof,”
“herein” and words of similar import are references to this Agreement as a whole and not any particular section or other provision of this Agreement. Whenever the context may require, any pronoun includes the corresponding masculine,
feminine, and neuter forms. All references to “dollars” or “$” will be deemed references to the lawful money of the United States of America. Further, the parties hereto have participated jointly in the negotiation and drafting
of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any
party hereto by virtue of the authorship of any provisions of this Agreement. All annexes attached hereto are hereby incorporated herein by reference and made a part hereof.

with this Agreement and the transactions contemplated hereby, including accounting and legal fees, shall be paid by the party incurring such expenses.

Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under the Agreements. The decision of each Purchaser to
purchase the Shares pursuant to the Agreements has been made by such Purchaser independently 

  
 - 29 - 








 
of any other Purchaser. Nothing contained in the Agreements, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association,
a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Agreements. Each Purchaser acknowledges
that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Shares or enforcing
its rights under this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be
joined as an additional party in any proceeding for such purpose. 
 10.12    Amendments and Waivers. No term of
this Agreement may be amended or modified without the prior written consent of each party hereto. No provision of this Agreement may be waived except in a writing executed and delivered by the party against whom such waiver is sought to be enforced.

Agreement: 
 (a)    “Affiliate” of any Person shall mean any other Person directly or
indirectly controlling or controlled by or under direct or indirect common control with such Person. For purposes of this definition, “control” when used with respect to any Person has the meaning specified in Rule 12b-2 promulgated under the Exchange Act; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 

(b)    “Company Material Adverse Effect” shall mean any change, development, occurrence,
or event that would reasonably be expected to be materially adverse to (i) the business, properties, assets, liabilities, consolidated results of operations, or financial condition of the Company and its Subsidiaries, taken as a whole; or

Subsidiaries operate; (2) any conditions affecting the United States of America’s general economy or the general economy in any geographic area in which the Company or its Subsidiaries operate or developments or changes therein or the

failure by the Company or its Subsidiaries to meet any internal or public projections, forecasts, estimates, or guidance for any period (it being understood that the underlying circumstances, events, or reasons giving rise to any such failure can be
taken into account in determining whether a Company Material Adverse Effect has occurred or would reasonably be expected to occur); or (10) any legal claims or other proceedings made by any of the Company’s stockholders (on their own
behalf or on behalf of the Company) arising out of or related to this Agreement; provided, however, that the changes, developments, occurrences, or events set forth in clauses (1), (2), (3), (4), and (5) above may be taken into
account in determining whether there has been or is a Material Adverse Effect if and only to the extent such changes, developments, occurrences, or events have a disproportionate impact on the Company and its Subsidiaries, taken as a whole, relative
to banks and bank holding companies in the United States of America.
